Example of Faith

I know that I have not written anything for a very long time. I apologize for that. Life gets very busy sometimes and we forget things. I decided it was time that I posted something new and hopefully meaningful.
I have been studying the topic of faith lately. My desire is to have a fuller understanding of saving faith in order to teach my children correctly and completely. When I entered college and adulthood, my knowledge of faith was limited to a few select verses and many analogies. I want to give my children many verses and maybe a few analogies.
One of the amazing things that I discovered in my study was that "blind faith" is not real faith. Paul made the statement, "We walk by faith, not by sight," (2 Corinthians 5:7) but that is not blind faith. The difference is between seeing what is not there verses not seeing anything at all. Here is what I mean.
Blind faith simply is accepting anything at all without evaluating or recognizing what has been promised. Blind faith does not see anything at all. Real faith sees what eyes cannot see. Real faith sees with the "eyes of the heart".
As an example of this, Paul talks about the faith of Abraham in Romans 4. He refers back to the promise God had made to Abraham, saying, "Your descendants will be as numerous as the stars in the sky." (Genesis 15:5) To that point, Abraham had no offspring; yet he believed God's promise.
Paul continues by pointing out, "In hope against hope he believed, so that he might become a father of many nations according to that which had been spoken, 'So shall your descendants be.' Without becoming weak in faith he contemplated his own body, now as good as dead since he was about a hundred years old, and the deadness of Sarah's womb; yet, with respect to the promise of God, he did not waver in unbelief but grew strong in faith, giving glory to God, and being fully assured that what God had promised, He was able also to perform." (Romans 4:18-21)
Basically, we can say that Abraham had a faith that was not blind to the problem of the promise. That is to say, Abraham recognized that he was too old to have children and his wife was unable to bear children; yet, the physical limitations did not reduce his faith in God to fulfill the promise. It is as though Abraham said, "God, I don't understand how you are going to produce descendants for me, but I believe you."
Hebrews points out, "But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul. Now faith is the assurance of things hoped for, the conviction of things not seen. For by it the men of old gained approval." (Hebrews 10:39-11:2) Saving faith is an "eyes-wide-open" belief in the promise of God which sees the promised future as though it were a present possession.
Like Abraham, we understand the problem with the promise. Paul pointed out that the message of the cross was "to the Jew a stumbling block and to the Greek foolishness." (1 Corinthians 1:23) The gospel makes no sense to the 'thinking man' because the problem of man's sin and God's righteous justice should not be able to be dealt with by the death of one man. How can one man's death provide pardon for all mankind? It does not make sense, yet God has chosen the foolishness of this world to confound the wise. Our response is either, "Yes, I believe," or "I cannot believe that!"
So we conclude with Paul, "But what does it say? 'The word is near you, in your mouth and in your heart'- that is, the word of faith which we are preaching, that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation." (Romans 10:8-10)
